Flood damage can have devastating financial consequences - nearly 40% of small businesses never reopen after experiencing a disaster like flooding. Understanding how to prevent flood damage can be the difference between thousands of dollars in damages and a resilient business that can bounce back quickly after a storm. 

As spring approaches, melting snow, seasonal storms, and rising water levels can put commercial properties at increased risk of flooding. Many businesses, especially those that have recently moved into a commercial property, may not be aware of their risk. This is often due to outdated flood zone maps or an increased flood threat in their area. 

Here’s how to know whether your business is at risk of flooding this spring and how to prevent flood disasters.

1. Your Property is in a High-Risk Flood Zone

If your commercial building is in a designated floodplain or near bodies of water, your risk of flooding is significantly higher. Check FEMA’s Flood Map or consult with a flood risk specialist to determine your property's flood zone status.

How to Prevent Flood Damage in a High-Risk Zone:

• Install custom flood barriers to protect entry points, elevators, underground parking, and other vulnerable areas. 
• Elevate critical systems like electrical panels, HVAC units, and backup generators. If you can’t, custom flood protection boxes are available to keep equipment safe.
• Consider flood insurance for financial protection.

2. Poor Drainage Around the Property

Standing water, slow-draining parking lots, or overflowing gutters are clear indicators that your drainage system is inadequate. Blocked or inefficient drainage increases the likelihood of water pooling around your building and seeping inside.

How to Prevent Flood Damage From Poor Drainage:

• Regularly clean gutters and storm drains of debris.
• Install French drains or sump pumps to redirect water away from your property.
• Ensure your property has proper grading to guide runoff away from the building.

3. Cracks or Gaps in the Foundation

Even small cracks in the foundation can allow water to seep into your building. When combined with spring rains or melting snow, these vulnerabilities can lead to significant interior flooding.

How to Prevent Flood Damage Due to Foundation Issues: 

• Seal cracks in the foundation with waterproof coatings or sealants.
• Apply waterproof membranes to walls and basements.
• Inspect your foundation regularly for new or worsening damage.

4. Nearby Stormwater Systems Are Overloaded

If your commercial property is in an area prone to heavy rain, an overwhelmed municipal stormwater system can cause street flooding that spreads to nearby buildings.

How to Prevent Flood Damage From Backed-Up Water:

• Install backflow prevention valves to keep sewage from backing up.
• Install floor drain flood barriers that effectively prevent water backup. 
• Work with local authorities to improve stormwater management in your area.
• Have a flood emergency plan in place to protect your business.

5. Previous Water Damage or Flooding History

If your building has experienced past flooding, it is at risk of future incidents - especially if previous damage was not properly addressed.

How to Prevent Flood Disruptions From Repeat Events: 

• Conduct a professional flood risk assessment to identify weak points.
• Invest in flood-resistant materials like water-resistant drywall and sealed concrete.
• Create a business continuity plan to minimize downtime in case of flooding.
